We began our quest for energy independence in the late 1980s. These photos show the system between 1999-2004

In 2003, we became aware that Pennsylvania has more radiant energy in the summer than Arizona in the winter, so we built a rack for the back of the coach.....

.....to transport  the panels for the ground array between Arizona and Pennsylvania

The system includes two 3 kw Statpower Prosine inverters and two stacked Trace SW4024 inverters, which can supply 240VAC so we were easily able to supply power to our home in Pennsylvania

As of 2009, we substantially increased the number of PV panels. We have abundant power and sometimes have to look for ways to use it so we don't overcharge the battery bank.
